Hi:

I've this WS2812B led stick

(attached Datasheet of Nulsom family LED components). I've tried with Arduino Neopixel library on Arduino IDE and with WS2812B library from Cableguy with no luck.

After googling, I've find this library that works Ok on Arduino IDE. (attached library + Arduino UNO examples)

Someone can wrap it to B4R ??

Thanks

Sorry, tested again with Erel's Adafruit library and works fine !

Please try the attached library.

B4X:

Sub Process_Globals
   Public Serial1 As Serial
   Private rb As NSRainbow
End Sub

Private Sub AppStart
   Serial1.Initialize(115200)
   Log("AppStart")
   rb.Initialize(1, 9)
   rb.SetColor(0, 255, 0, 0)
   rb.Show
End Sub

If it is working then you should post a picture...

Sorry, I've tried the Cableguy code for W2812B but didn't search for B4R Adafruit library ;-(

I've tried the wrapped library but didn't work . I don't know if it matters but which are the values for rb.initialize ?
(first the number of leds on the strip and second the Arduino pin used as Din ?)
